The part of through-hole, this type of attachment are known as being bolted.When installing and using, nut holds bolts and nuts in the prior art
Easily there is the loss that loosens and then fall off from bolt, it is more inconvenient, influence actual install and use.
Utility model content
Purpose of the utility model is to solve exist in the prior art nut be easy fall off from bolt the shortcomings that, and
A kind of bolt assembly proposed.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of bolt assembly, including screw bolt and nut are designed, the bolt, which is connected by head with bar portion, to be formed, the bar portion
It is composed of a fixed connection by the smooth shaft and threaded rod of concentric setting, the smooth shaft is far from one end and head of threaded rod
Portion is fixedly connected, and the nut is set in the outside of threaded rod and is threadedly coupled with it；
The inside of the one end of the threaded rod far from smooth shaft offers tapped blind hole, the tapped blind hole position along its axial direction
In the center point of threaded rod, the internal whorl of the tapped blind hole is connected with fastening screw, the outer end connection of the fastening screw
There is limited block, the limited block is respectively connected with the support rod for being parallel to fastening screw, the nut close to the two sides of the one side on head
Two end faces on offer annular arrival slot corresponding with support rod position along its circumferential direction.
Preferably, the outer cover of the smooth shaft is equipped with gasket, and the gasket is set as rubber sheet gasket.
Preferably, the support rod is set as arc surface far from one end of limited block, and annular arrival slot is set as arc arrival slot.
Preferably, the fastening screw is identical as the length of support rod, and the length of the fastening screw is less than the length of threaded rod
Degree, and the length of fastening screw is greater than the half of screw thread pole length.
The utility model proposes a kind of bolt assembly, beneficial effect is: the utility model have design rationally and
The advantages of convenient for operating with, installs and uses at the case where effectively nut capable of being avoided to fall off from bolt convenient for actual.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of bolt assembly structural schematic diagram；
Fig. 2 be the utility model proposes a kind of bolt assembly cross-sectional view.
In figure: head 1, bar portion 2, smooth shaft 3, threaded rod 4, nut 5, limited block 6, fastening screw 7, support rod 8, gasket 9,
Tapped blind hole 10, annular arrival slot 11.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of bolt assembly, including screw bolt and nut 5, bolt are made of head 1 and the connection of bar portion 2, bar
The smooth shaft 3 and threaded rod 4 that portion 2 is arranged by concentric are composed of a fixed connection, the one end of smooth shaft 3 far from threaded rod 4 and head 1
Middle part be fixedly connected, nut 5 is set in the outside of threaded rod 4 and is threadedly coupled with it.The outer cover of smooth shaft 3 is equipped with gasket
9, gasket 9 is set as rubber sheet gasket, and the fastening effect of bolt assembly entirety can be improved in gasket 9.
The inside of the one end of threaded rod 4 far from smooth shaft 3 offers tapped blind hole 10 along its axial direction, and tapped blind hole 10 is located at
The center point of threaded rod 4, the internal whorl of tapped blind hole 10 are connected with fastening screw 7, and the outer end of fastening screw 7 is connected with limit
Block 6, limited block 6 are respectively connected with the support rod 8 for being parallel to fastening screw 7, two ends of nut 5 close to the two sides of the one side on head 1
Annular arrival slot 11 corresponding with 8 position of support rod is offered along its circumferential direction on face.Support rod 8 is arranged far from one end of limited block 6
For arc surface, and annular arrival slot 11 is set as arc arrival slot, and setting in this way is convenient for the support rod 8 when turning of limited block 6 to support in annular
It is moved in slot 11.Fastening screw 7 is identical as the length of support rod 8, and the length of fastening screw 7 is less than the length of threaded rod 4, and fastens
The length of screw rod 7 is greater than the half of 4 length of threaded rod, and setting in this way has support rod 8 to nut 5 preferable convenient for actual use
Limit effect.In actual use, be folded between nut 5 and head 1 by fastener, 5 pairs of nut by fastener have compared with
Fastening screw 7 is plugged in tapped blind hole 10 after the position of nut 5 is fixed, turns fastening screw 7 by good limit effect,
Support support rod 8 in the annular arrival slot 11 being located on nut 5, support rod 8 has preferable restriction effect to nut 5, can effectively avoid
There is the case where loosening and falling off from threaded rod 4 in nut 5, installs and uses convenient for actual.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
